Overview
- Officials say this is the first medically driven early end to an ISS mission and the first such NASA mission termination in more than 65 years.
- Undocking is targeted for Jan. 14 at 5 p.m. ET with a planned splashdown off the California coast on Jan. 15, pending weather and recovery conditions.
- NASA has not disclosed the affected crew member’s identity or diagnosis, stating the issue is unrelated to station operations and not an injury.
- A planned spacewalk was canceled as teams shifted to medical and operational priorities, and station activities are being adjusted.
- ISS operations will continue with a reduced crew, including U.S. astronaut Christopher Williams and two Russian cosmonauts, with some research and maintenance likely delayed.
